Saffron compounds and effects on the nervous system

What it found

Saffron and its active compounds have shown protective, calming, antidepressant and memory-enhancing effects in lab and human studies.

The plant could be a useful medicinal food ingredient for nervous system disorders.

What they found

Studies in people and animals

Nervous system effects

Lab and human studies have supported protective, calming, antidepressant and memory-enhancing effects of saffron and its compounds safranal, crocin and picrocrocin.

Other findings

Active compounds

Saffron contains apocarotenoids, monoterpenoids, flavonoids, phenolic acids and phytosterols. These have been widely investigated for therapeutic effects.

Reaching the brain

Some active compounds in saffron are well absorbed and can pass the blood-brain barrier. This means they can reach the nervous system.

What the authors conclude

  • They say saffron and its active compounds could be a beneficial medicinal food ingredient in drugs targeting nervous system disorders.

How it was done

Saffron is used traditionally in Chinese, Ayurvedic, Persian and Unani medicines. The authors wanted to review its chemistry and its effects on the nervous system.

The authors reviewed experimental and clinical studies on saffron's bioactive compounds, including how well they are absorbed and whether they can reach the brain.

What it can’t tell you

  • We summarised it from the abstract only.
  • This is a review of other studies, not a new experiment. It cannot prove that saffron itself causes these effects in people.
